I assembled mine form a variety of parts I purchased form a bike shop, I believe everything was just under $12. The sales person assisting me asked me what bike was the shifter was for, I told him it was for a Jeep. He said he would have to take a look at the bike as he was certain that it was a re-badge "Huffy" or other low end bike, labeled with the ďJeepĒ brand. I told him he was mistaken but he was persistent and told me that he had previously seen a Jeep bike come in the shop for repair. He proceeded to ask me if I had the bike with me and I said it was out in the parking lot. He wanted to have a look to see if one of the "universal" shifters would fit. When we were outside, he asked where the bike was, I showed him the Jeep - the poor guy was so confused
I explained what I wanted to do and the purpose of the shifter, and he finally set me up with the right components to piece a viable throttle solution
Since I have an automatic, I elected to mount my throttle closer to where my hand rests on the steering wheel. It works for me, although I have received a few comments that it may not work well - being in such an awkward location (Iím left handed, Iím used to many things placed in an awkward position, my hand throttle isnít). However for many, the shifter is the best location as it is a natural area to rest oneís hand while driving. I personally donít rest my hand on my auto shifter; itís usually on the steering wheel. Another benefit for me is when Iím outside of the Jeep, I can easily reach in and adjust my rpms for winching or when using my air compressor.
